ControllerRunnable interface: implemented by controller
ControllerContext: Controller Context for controller execution
ControllerPreparable interface:used to setup execution context
ControllerExecutionBB:controller execution for building block
ControllerExecutionDE:controller execution for camunda
Skeleton implementation for APPC controller
Skeleton implementation for SDNC controller
Use ControllerExecutionDE for existing PNF configuration.
